The rear flap includes a positioning element (6) that is automatically moved in the opened position by a moving mechanic (4), a fold-like element (14) is designed as a covering part and tray is arranged on the moving mechanic. The fold-like element is movably coupled over a bind or rope-shaped traction unit (18) i.e. Bowden traction unit, with the movement mechanic in such a manner that the element lies in a horizontal plane independent of a position of the rear flap.

Description

The invention relates to a motor vehicle comprising one of a cavity covering a closed position in an open position and vice versa movable tailgate, which is automatically movable via a movement mechanism comprising an actuator at least in the open position, and on which, with her mobile, serving as a cover or tray Element is arranged foldable.

To be able to use existing storage space as optimally as possible, it is for example DE 197 14 497 A1 known to arrange below the tailgate serving as a cover or tray folding element that, when closed, a receiving space below the tailgate limited, can be stowed in the lighter items. At the DE 197 14 497 A1 Known system three flap-like elements are provided on the tailgate inside, each defining three recording rooms in which, for example, sound carriers in the form of CDs or for example a warning triangle or the like can be introduced. The opening and closing is done manually by the flap-like element is released from its fixation on the tailgate after complete opening of the tailgate, so that it can be opened. This manual operation is disadvantageous since at least one handle for opening and closing is required for each stowage or removal operation.

The invention is therefore based on the problem to improve a motor vehicle of the type mentioned in that the stowage and removal of objects is simplified.

To solve this problem, the invention provides that the element is coupled via a band or rope-shaped traction means in such a way with the movement mechanics that the element always harbors regardless of the position of the tailgate in the horizontal.

In the motor vehicle according to the invention, the flap-shaped element is coupled in motion via a band or rope-shaped tension element with the movement mechanism of the tailgate, so that when the tailgate is opened or closed, during the movement process always remains almost in the horizontal. This means that when swinging the tailgate, the flap-like element, although with the tailgate, where it is pivotally mounted at one end, is slightly moved up, but at the same time with the front end quasi tracked, so that the element overall despite increasing the opening angle of Tailgate remains almost horizontal. This means that the opening angle of the element relative to the tailgate increases, as it were, almost opposite to the increase in the opening angle of the tailgate. Conversely, when closing the tailgate when the opening angle of the tailgate is reduced, in the opposite direction, the opening angle of the element is reduced. It is attracted by the traction means directed opposite to the tailgate, in turn, however, so that it remains almost in the horizontal during this movement.

To ensure this, a corresponding band or rope-shaped traction means is provided, which is coupled to the movement mechanism of the tailgate. About this traction means on which hangs the tailgate with its free, not pivotally mounted and aufklappenden end, the folding element movement is controlled. Over this quasi band or rope length is added or shortened, so that the horizontal orientation of the element is maintained regardless of the tailgate angle.

This process is automatic, which means that when opening the tailgate, the flap-shaped element automatically pivots away from the tailgate. In the case of closing the tailgate, it automatically re-engages the tailgate. Manual activities to open and close the element are not required. If, for example, the tailgate is to be opened automatically via a radio control, then the operator merely has to press the radio remote control, whereupon the tailgate opens automatically, but automatically the element also folds down and opens the storage space defined above. Closes the tailgate again automatically, for example, in which a button on the tailgate or again the radio remote control is operated, the tailgate is closed automatically via the movement mechanics, in parallel is also pivoted by appropriate Zugsmittelbewegung the element to the tailgate. This is very convenient for the user since sometimes he does not necessarily have a hand free to perform any activities required to open and close the element.

The element is preferably a component that extends over a major portion of the tailgate width and serves as a storage element, for example for receiving a garment such as a jacket or a jacket or the like, as well as other loose objects such as magazines, books, and the like are stowed here can.

Preferably, two movement mechanics are provided, each comprising an adjusting element, wherein the element is coupled in motion via two traction means, each with a movement mechanism. That is, the element according to the invention at both free sides respectively corners is suspended in each case via a traction means and is coupled to the movement mechanism so that it is fixed on the one hand tailgate side on the pivot bearing, on the other hand suspended at the free end on the two lateral traction means. This also ensures that something even heavier objects can be introduced.

The or each band or rope-shaped traction means is guided accordingly on or along the movement mechanics, so that the free length of the traction means varies in the manner of a pulley on actuation of the tailgate movement actuating element, thus band or rope length is added when the tailgate is opened and the element is to swing away from the tailgate, or the band or rope length is shortened when the tailgate is closed. For this purpose, the or each traction means can be arranged fixed in position with one end and connected to the other end with the element. The traction means is guided accordingly via corresponding deflection pins or rollers or the like, wherein the traction mechanism is of course designed so that when moving the movement mechanism and taking into account the change in this opening angle, the corresponding flaschenzugartig band or pitch variations.

It is also expedient if the or each traction means is stretched over a spring element. This means that at any point within the movement coupling of the element to the movement mechanism, a spring element is integrated, which can be lengthened if necessary to a certain extent, thus thus provides for a sufficient degree of elasticity. This serves to prevent too high rope tensions. If, for example, a relatively heavy object is placed on the element, a tensile force is exerted thereon on the one or both traction devices. In order to prevent this from becoming too great and from damage occurring in the context of the traction mechanism guide or from tearing of the traction means itself, a certain resilience is realized via the spring element, that is to say that the element can pivot downwards by a few degrees. about which the spring is elongated, for example. Thus, the spring biases the traction means, while also allowing a certain flexibility. The spring element can be integrated in the traction means, that is, that the traction means consists of two Zugmittelteilen, which is connected via the spring element. But it is also conceivable that the traction means is connected at one end to the spring element, which in turn is connected to the element or the movement mechanism or fixed in position. It is conceivable, for example, the use of a coil spring or the like.

Conveniently, the or each traction device is designed as a Bowden cable, consisting of the actual traction cable itself, as well as a stable, both sides clamped shell, in which the actual traction cable is guided.

According to an advantageous embodiment of the invention, the element can be stored with its tailgate end mounted on two double hinges. Under a double hinge according to the invention a hinge understood, which ultimately has two bearings. In the region of the first bearing point, the element is pivotally mounted on the hinge, that is, it pivots about this bearing axis relative to the tailgate. The second bearing allows the element to have some linearity relative to the tailgate. This means that the element can also move a few centimeters linearly guided away from the tailgate, which is required, for example, when a slightly thicker or higher object is introduced, which is slightly larger or higher than the receiving space between the element and the tailgate. This linear mounting of the element now makes it possible for the element to be able to move slightly away from the tailgate in the region of this double-hinge bearing, thus increasing the volume and also allowing a somewhat thicker object to be introduced while balancing the receiving space height.

The element itself can be made overall relatively stiff, so therefore be a sufficiently stable flap or the like. It is also conceivable, however, from a stiffer frame, in which a flexible textile material is stretched execute. The textile material thus forms a kind of flexible net within the frame, which has a certain basic flexibility.

Further advantages, features and details of the invention will become apparent from the embodiment described below and with reference to the drawings. Showing:

1 a schematic diagram of a motor vehicle according to the invention with closed tailgate,

2 the motor vehicle 1 with partial open tailgate and

3 the motor vehicle 2 with fully opened tailgate.

1 shows a motor vehicle according to the invention 1 comprising a tailgate 2 around a pivot axis 3 can be pivoted in a well-known manner, as indicated by the arrow A is shown. For automatic swinging, possibly also for automatic closing, is a movement mechanism 4 provided, comprising one with an end 5 Body-mounted control element 6 For example, an actuating cylinder, with the other end 7 on a pivot lever 8th attacks. The swivel lever 8th with a pivot bearing 9 Body-fixed, stored. On the other end 10 of the pivot lever 8th is a pole 11 hinged to the other end 12 in the tailgate area 2 is attached.

The basic function is to open the tailgate 2 such that upon actuation of a trigger mechanism, the actuator 6 is pressed. It drives with its piston rod 13 from, where there is a pivoting movement of the pivot lever 8th , as shown by the arrow B comes. This is the rod 11 starting from 1 pushed up, what about a pivoting movement (arrow A) of the tailgate 2 around the pivot axis 3 comes and the tailgate 2 from the in 1 shown closed position over the partially open position according to 2 in the open position according to 3 arrives.

On the tailgate is further serving as a cover or storage, flap-like element 14 arranged on a tailgate panel 15 around a hinge 16 , which is preferably designed as a double hinge, is pivotally mounted. The element 14 So can relative to the tailgate 2 respectively the tailgate trim 15 be pivoted and between a closed position in which a recording room 17 completed, and an open position in which this recording room 17 is opened, moved.

This movement is fully automatic during the movement of the tailgate 2 itself. For this purpose, according to the invention, a band-shaped or rope-shaped traction means 18 intended. This is with an end 19 positionally fixed or body side arranged. The drawstring or traction means 18 is then a deflection roller 20 on the pivot lever 8th is arranged, guided and runs from there to a deflection roller 21 At the rod 11 so it runs parallel to the pole 11 , From there it runs over another, provided in the tailgate position-fixed pulley 22 to the element 14 where it ends with the other 23 is attached. The traction device 18 is in the example shown with an integrated elasticity 24 provided here, for example, a biasing coil spring, which prevents it at a greater load on the traction device 18 resulting from one in the recording room 17 introduced, heavy object, damage occurs.

About this traction device 18 is now a fully automatic opening and closing process of the element 14 possible, in such a way that the element 14 during the entire time remains almost horizontal, regardless of how concretely the opening angle of the tailgate 2 as such is. The actual function results from the 1 - 3 ,

1 shows the tailgate 2 in the closed state. The element is obvious 14 pivoted adjacent to the tailgate 2 , the recording room 17 is closed. The swivel lever 8th is located in a pivoted to the left position, the actuator 6 has moved in.

Now, for example, by pressing a radio trigger the automatic opening process of the tailgate 2 initiated, it unlocks. Connected with it is also the actuator 6 released, see 2 , The piston rod 13 moves out of the cylinder, the pivot lever 8th is about the pivot bearing 9 pivoted as shown by the arrow B. Its lower end wanders up a bit, which causes the pole 11 is also pushed up. Also connected with this movement is a tailgate swiveling up 2 , Connected to the pivoting movement of the pivoting lever 8th or the rod 11 but is also a movement of the traction device 18 , the pulley pull over the various pulleys 20 . 21 . 22 is guided. As a result of the pivot lever movement, the traction means 18 in the direction of the element 14 moved respectively released, that is, I quasi the free length of the traction device 18 from the pulley 22 to the end 23 , ie the articulation point, to element 14 , enlarged. This is shown by the arrows C. This traction means movement now causes the element 14 , as shown by the arrow D, due to gravity around the hinge 16 something swings around. The relative movement of the traction device 18 is dimensioned such that the element 14 during the swiveling movement of the tailgate 2 remains almost permanent in the horizontal plane, which it, starting from 1 where it may be slightly sloping, immediately with the initiation of the opening process already occupies.

Now pans from 2 the tailgate 2 continue on, so the piston rod moves 13 always further from the cylinder of the control element 6 In addition, the pivot lever 8th will always continue around the pivot axis 9 swung. The pole 11 As a result, is pushed further and further up, so the tailgate 2 always up to the maximum opening position according to 3 is pivoted. Connected with this, however, is also a further tracking of the traction device 18 in the direction of arrows C, associated with an increase in the opening angle α between the element 14 and the tailgate 2 itself, being, like 3 shows the element 14 is still horizontal. The However, opening is fully automatic, any manual handles are not required. At the latest in the in 3 shown open position, it is readily possible objects, especially lighter items such as a jacket or the like on the element 14 store. The deposited object is in the closed position, see 1 , then certainly in the relatively large-volume recording room 17 added.

The closing movement is exactly the reverse, that is, all movements go in the reverse direction from equip. The tailgate 2 is, starting from 3 , either automatically or manually moved down. As a result of this movement is over the bar 11 also the swivel lever 8th in the opposite direction, ie starting from 3 to the left, pressed. The piston rod 13 is inserted into the cylinder. Associated with this is also a retraction of the traction device 18 , It comes parallel to the lowering movement of the tailgate 2 to a relative lifting movement of the element 14 which, however, remains horizontal. This movement takes place until the closed position according to 1 is reached.

Preferably, the entire movement mechanism comprising all described components such as actuator, rod, traction means, etc. is provided in duplicate, ie on both sides of the tailgate, so that it is safely raised or lowered via a reciprocating motion mechanism. But it is also connected to that element 14 on both sides via a traction device 18 is suspended and is also safe. This double suspension also makes it possible to pick up something heavier. A possible heavier load on the traction means 18 is about the integrated spring elements 24 , which of course can be positioned elsewhere, balanced. In addition, the introduction of slightly higher objects, which are slightly higher than the recording room 17 To allow, it is expedient if the hinges provided on both sides 16 are designed as double hinges, which not only allow the actual pivoting movement, but also a linear movement of the overlying end of the element 14 relative to the tailgate 2 respectively the tailgate cover 15 ,

Of course, other embodiments are conceivable. So can the or each actuator 6 Also as a double-acting actuator, which thus allows an automatic opening and an automatic closing movement, be designed, for example, as a double-acting or controllable actuating cylinder or as a ball screw or the like. Also, of course, the leadership of the traction device 18 be something, as long as it is designed so that it comes to a defined traction means movement, which ensures that the element regardless of the opening angle of the tailgate 2 always remains essentially horizontal.
